I am so delighted that my November 2021 river cruise is a "go." Equally exciting is for entry to Iberia, I only have to show my CDC vaccination card. No COVID testing required. Spain does require an on-line affidavit/health questionnaire that has to be completed before departure from the U. S. I haven't looked at it yet. Come November, it might not be required. If returning to the U. S. from Spain, a negative COVID test is required; however, this is not required if returning from Portugal. This is as of today, so things can obviously change. Tauck even contacted me today to advise that my flight departure from LAX has a time change...a five minute time change! They are the best!
